Problems solved by technology

With the advancement of technology, the texture of ceramics is also constantly improving. There are a wide variety of ceramic products on the market, and their practicality and decoration are relatively strong. Surface patterns are used to improve viewing, such as underglaze images and surface relief-like three-dimensional effects. However, due to the influence of technology, the surface of pattern images often appears uneven, which affects its large-scale promotion and application, and still needs technical improvement.

Embodiment Construction

[0011] The ceramic underglaze imaging process of the present invention, the specific process steps are as follows: firstly, the conceived pattern is engraved on the surface of the gypsum through negative carving and positive carving, and the image pattern is transferred to the surface of the gypsum to make a seal; Transfer to the wet ceramic body to form a three-dimensional engraved image on the ceramic body; then first glaze the body around the pattern, and then evenly spread the frit powder on the pattern, and the frit The amount of powder can be adjusted according to the volume of the depression in the pattern. If the volume of the depression is large, it can be sprinkled more, and if the volume of the depression is small, it can be sprinkled relatively less; finally, the green body is put into the kiln and fired according to the following temperature curve: the first stage of heating In 2 hours, the temperature is raised from room temperature to 400°C at a constant speed; i...

Abstract

The invention a process for preparing an image under a ceramic glaze. The process is characterized by comprising the following steps: preparation of a gypsum image stamp: engraving an image pattern on the surface of gypsum so as to prepare the stamp; transfer printing of the pattern: carrying out transfer printing by using the stamp so as to allow the pattern to be transferred to a wet ceramic green body; glazing: glazing the part of the green body surrounding the pattern and uniformly spraying first-grade frit powder to coat the pattern on the green body; and feeding of the green body into a furnace and sintering. According to the invention, the first-grade frit powder is separately applied onto embossing image; thus, the surface of the image under the sintered ceramic glaze is smooth, the pattern is glistening, demands for beautiful appearance are met, practicality is improved, and a ceramic surface is easier to clean and free of accumulation of dirt.

Description

technical field [0001] The invention relates to a ceramic preparation process, in particular to a ceramic underglaze imaging process. Background technique [0002] my country's ceramics have a long history and are an outstanding representative of the progress of human civilization. They are now spread across all areas of our lives and improve our quality of life. With the advancement of technology, the texture of ceramics is also constantly improving. There are a wide variety of ceramic products on the market, and their practicality and decoration are relatively strong. Surface patterns are used to improve viewing, such as underglaze images, surface relief-like three-dimensional effects, but due to the influence of technology, the surface of pattern images often appears uneven, which affects its large-scale promotion and application, and still needs technical improvement. Contents of the invention [0003] In order to solve the above problems, the present invention provid...
